I think there should be some psychological testing to make sure that you're not really recruiting people who would be violent, who have difficulty working with women or who don't have any respect for the people they work with, whether they be men or women.
The model that you give of a policeman should be different from what it was in the past, and I'm not sure that it is this way now. I think people are conscious of the fact that there has to be a different outlook when you're recruiting people and when you're setting them on a continuum for training, obtaining promotions and then exercising leadership roles.
